If creationism is science, you should be able to answer these questions:
What is creationism?
Many people find that the most important part of a theory is a clear description of what the theory says and does not say.
(1) Give a comprehensive statement of creationism. (There are questions below about conventional science, so please restrict your discussion here to the positive aspects of creationism.) This is the one question of over-reaching importance, so much so that you might consider many of the following questions merely asking for certain details of what makes up a comprehensive statement of creationism. It should be noted that many people prefer quantitative details where appropriate.
It is often a great help to communication if each party understands what the other means by certain critical expressions.
(2) Define technical terms and other words or expressions that are likely to be misunderstood.
(3) Include the evidence for creationism (please remember that merely finding problems with conventional science does not count as support for creationism, as there may be other theories which differ from both conventional science and creationism). A good example of evidence for creationism would be some observation which was predicted by it. That is much better support than merely giving an explanation for observations which were known before it was formulated. Far less convincing is evidence which has an alternative explanation.
In order to decide between conflicting theories, it is important that not only must the conflicting theories be well described, and that the evidence supporting the conflicting theories be proposed, but also that there be established some rules for deciding between the theories and evaluating the evidence.
(4) Can you suggest principles for so deciding and evaluating?
There are many alternatives to creationism. Some of the alternatives are: theistic evolution and old-earth creationism.
(5) Distinguish your theory of creationism from some of these alternatives and give some reasons for it rather than the others.
Many people find a theory which is open to change in the face of new evidence much more satisfying than one which is inflexible.
(6) Describe features of creationism which are subject to modification. Another way of phrasing it is: is there any kind of observation which, if it were seen, would change creationism? Is it open to change, and if so, what criteria are there for accepting change?

Nice segue but it doesn't help you a bit. You stated that "there are no creationists who do science". The statement is false. A creationist, by definition, is somebody who believes that God created the Universe and all that is in it. That seemingly describes all Christians, except you.
To prove your statement false, one would simply have to name one creationist who did science. There have been literally millions of them.
I leave it as an exercise for you to set your straw dog aflame.
